I never said it isn't worth doing....I said it is rarely worth doing.
Quite frankly most of the time, the points you will drop from shooting on the move (on targets that aren't in your face) does not make up for the time that you save.
Take Max for example....He too rarely shoots on the move, yet stomps the crap out of everyone else.
The way I look at it....when deciding to shoot an array of targets on the move, there are a few things that need to be known. First...shooting on the move will for the most part greatly increase your time between positions, you will shoot slower, and have sloppier hits. Most of the time this does not offset running to the next position, getting a nice practiced fluid set up, and shooting the targets faster with better hits.
Each puzzle has a different solution....sometimes it is worth it, often it isn't.
